[0053] In the embodiment, the zongzi is placed in the vacuum packaging bag 5, and the soup is injected in the rotating process. Under the action of centrifugal force, the soup can be better squeezed into the zongzi, that is, better squeezed into the gap of the rice grains, so as to avoid excessive bubbles generated by subsequent heating. After being cooked and vacuum water injection packaging, no bubbles are generated because the rice grains have absorbed enough water, and the soup has filled the gap between the rice grains in the process of boiling. Through the cooperation of the clamping assembly 3 and the water injection assembly 4, the work of water injection, vacuumizing, and sealing can be completed in the rotating process. Before packaging, each zongzi needs to be weighed, and the soup is added according to the weight of the zongzi. The more the weight of the zongzi, the more the soup needs to be added, and vice versa. The mass ratio of the soup to the raw material is 15-18:100, and the volume mass ratio of the soup to the glutinous rice is not greater than 1:6. The sealing cover 102 is opened, the moving support 105 is driven upward by the first telescopic device 106, the moving of the moving support 105 drives the rotating assembly 2 to move upward, the upward movement of the rotating assembly 2 drives the clamping assembly 3 and the water injection assembly 4 to move upward, and when the clamping assembly 3 is located outside the processing shell 1, the clamping assembly 3 is clamped and fixed to the vacuum packaging bag 5. Then the zongzi is placed in the vacuum packaging bag 5, the two clamping housings 302 are moved in opposite directions by the two second telescopic devices 301, the movement of the clamping housings 302 drives the movement of the movable blocks 303, the two movable blocks 303 are moved in opposite directions, and then the opening of the vacuum packaging bag 5 is placed between the two movable blocks 303. The movable blocks 303 are clamped and fixed to the vacuum packaging bag 5 by the second telescopic device 301 (as shown in Figure 5 When all the clamping assemblies 3 are clamped and fixed with the vacuum packaging bags 5 containing zongzi, the first telescopic device 106 is controlled to contract, so that the rotating assembly 2 drives the clamping assembly 3 and the water injection assembly 4 to be located in the inside of the processing shell 1 again, and the sealing cover 102 is covered.

[0054] The weight of the zongzi is input into the corresponding water injection assembly 4, which will inject a certain amount of soup according to the weight of the zongzi. The specific steps are as follows: start the drive motor 108, which will drive the rotating assembly 2 and in turn the clamping assembly 3 and the water injection assembly 4 to rotate. The clamping assembly 3 will drive the vacuum packaging bag 5 containing the zongzi to rotate. In this process, the third telescopic device 307 drives the connecting block 308 to move, and the connecting block 308 drives the two movable blocks 303 to move in opposite directions. In the process of movement, the upper and lower movable blocks 303 will drive the upper and lower anti-slip wave-shaped clamps 304 to move in opposite directions. Taking the two anti-slip wave-shaped clamps 304 as an example, the total stroke of the movement of the two anti-slip wave-shaped clamps 304 is half of the wave shape of the anti-slip wave-shaped clamp 304. That is, through the relative movement of the two anti-slip wave-shaped clamps 304, the lowest point of the upper anti-slip wave-shaped clamp 304 can be moved to the highest point of the lower anti-slip wave-shaped clamp 304, so as to form a plurality of circles between the upper and lower anti-slip wave-shaped clamps 304. At the junction of the two anti-slip wave-shaped clamps 304, the relative position of the anti-slip wave-shaped clamp 304 and the movable block 303 changes when the anti-slip wave-shaped clamp 304 moves relatively. The anti-slip wave-shaped clamp 304 will overcome the elastic force of the compression spring 3041 to move. Since the friction between the anti-slip wave-shaped clamp 304, the anti-slip strip 305 and the vacuum packaging bag 5 is large, and the friction between the upper and lower layers of the vacuum packaging bag 5 is small, the anti-slip wave-shaped clamp 304 and the anti-slip strip 305 can drive the vacuum packaging bag 5 to deform when they move relatively. Finally, the vacuum packaging bag 5 follows the shape of the anti-slip wave-shaped clamp 304 and also forms a plurality of circular holes. It should be noted that the width of the vacuum packaging bag 5 is greater than the width of the anti-slip strip 305.

[0055] When the packaging bag follows the shape of the anti-skid wave-shaped clamp 304 and also forms multiple circular holes, the fourth telescopic device 402 is started, which drives the shunt shell 403 to move, and the movement of the shunt shell 403 drives the water injection pipe 407 to move, so that the water injection pipe 407 is inserted into the multiple circular holes formed in the packaging bag, and then the target amount of soup is injected according to the weight of the zongzi, and under the action of the centrifugal force, the soup is concentrated at the bottom of the vacuum packaging bag 5. When the target amount of soup is injected into all the vacuum packaging bags 5, the vacuum pump 104 is started, which gradually extracts the air inside the processing shell 1, and the air inside the vacuum packaging bag 5 is also extracted from the multiple circular holes formed, and in the process of extracting the air inside the vacuum packaging bag 5, the soup inside the vacuum packaging bag 5 gradually moves towards the bag opening. When the soup moves to the bag opening and contacts the water injection pipe 407, the water injection pipe 407 will be immediately extracted. The specific reason why the water injection pipe 407 is immediately extracted is as follows: when the soup flows out of the water injection pipe 407, the soup will contact the inner conductive ring 408. At this time, the soup only contacts the inner conductive ring 408. When the soup in the vacuum packaging bag 5 moves to the bag opening, the water in the vacuum packaging bag 5 will flood the head of the water injection pipe 407, that is, at this time, the soup will contact the inner conductive ring 408 and the outer conductive ring 409 at the same time. At this time, the inner conductive ring 408 and the outer conductive ring 409 are in electrical connection, and after electrical connection, the electrical signal can be transmitted to the control unit through the wire 4010, and the control unit will immediately control the contraction of the fourth telescopic device 402. After the contraction of the fourth telescopic device 402, the water injection pipe 407 is extracted from the hole formed in the vacuum packaging bag 5 and returns to the original position. Moreover, after the water injection pipe 407 is extracted, the control unit will immediately control the third telescopic device 307, which drives the connecting block 308 and then the movable block 303 to move back to the original position (i.e. Figure 5 The movable block 303 will again clamp and seal the bag opening of the vacuum packaging bag 5, and then the heating wire 309 is powered on, which will heat and melt the bag opening of the vacuum packaging bag 5.

[0056] It should be noted that a barrel for storing soup can be installed on the rotating support 201, and one end of the connecting water pipe 405 is fixed in communication with the barrel.

[0057] The packaged zongzi is placed in a sterilization pot, and a segmented heating method is used for sterilization. When the temperature in the sterilization pot reaches 121°C, the temperature is kept for 30 minutes, and then the temperature is segmentedly reduced to 50°C. After draining and exhausting, the pot is taken out. The segmented heating processing steps are as follows:

[0058] Step 01: gradually heat from room temperature to 90°C;

[0059] Step 02: first constant temperature sterilization. When the temperature in the sterilization pot reaches 90°C, the temperature is kept for 45 minutes.

[0060] Step 03: After the first constant temperature sterilization, gradually heat from 90 DEG C to 121 DEG C;

[0061] Step 04: The second constant temperature sterilization, when the temperature of the sterilization pot reaches 121 DEG C, heat treatment for 30 min;

[0062] The processing steps of the segmented cooling treatment are:

[0063] Step 11: After the second constant temperature sterilization, start cooling, the temperature drops to 110 DEG C, set the time for 2 min;

[0064] Step 12: When the temperature drops to 110 DEG C, start the second cooling, the temperature drops to 90 DEG C, set the time for 2 min;

[0065] Step 13: When the temperature drops to 90 DEG C, start the third cooling, the temperature drops to 50 DEG C, set the time for 2 min;

[0066] Step 14: Drainage, exhaust treatment, when the pressure value of the sterilization pot is 0 MPA, the sterilization is completed, and the pot is taken out in time;

[0067] By injecting a certain amount of soup into the inside of the zongzi, the raw materials can have sufficient water absorption, meet the requirements of zongzi water absorption and raw material curing degree, and through adjusting the formula of the soup, the taste of the zongzi can be changed, which is beneficial to improve the product diversity. The way of packaging first and then cooking also ensures the loss of nutrition and flavor in the subsequent processing process.
